Vokalzz
Another issue im running into is this.......
When I goto automate the track I use the green output meeter as a guide. For example: lets say I take the vocal part of the verse. I start to aline all the vocals between -12db and -18db, this way I can have some consistency between the vocals. However, even when I do that there are some parts that sound way louder then other parts even though all the vocals fall between the -12db and -18db range. Why is this?? Whats the best way to go about this?
Ah, that's because there's more than one way of measuring volume :-)
By default the green meter shows the peak volume. Which is the absolute maximum at that instant in time. Our ears and brains on the other hand tend to perceive volume as more as an average level. We filter out transient peaks and focus more on that average level.
What you need to keep an eye (and ear) on isn't just the peaks but the RMS level of the tracks/busses. RMS levels reflect our perception of volume much more than peak levels. A classic example is the guitarist who sets up a fuzz or distortion so it sounds deafening compared to their clean tone at home then finds on stage when they hit the footswitch at the start of their solo rather than their volume leaping up they disappear in the mix. The pedal is applying a lot of compression, which raises the RMS volume, so it sounds louder on it's own than the clean sound, but the clean peaks are actually much louder than the peak produced by the pedal. The apparent volume of things can be very deceptive.
Another example is banjos. The peak volume out of a good plectrum banjo might be 110dB or more at one metre (I've measured one so I know). But that's only for a few milliseconds as the pick hits the strings. The bulk of the output is much lower, which is a good thing because the transient volume if sustained would be literally deafening in a very short time. When we listen to a banjo it's that lower, average, volume our nervous system uses to assess how loud it is.
I suggest you set up Sonar's playback metering on tracks, busses and master to show RMS as well as peak volumes. You don't want the peaks to go over, but for consistent volume aligning the RMS volume to similar levels will produce a much more consistent sounding volume. If the gap between RMS and peak is so large you can't raise RMS without the oeaks going to high, reducing that difference is what compressors were invented for.
